EC50 with Service flashing is the fresh food side of the same warning: the refrigerator compressor has been running for too long.

Check the temperature in the fresh food section before you touch any buttons. If it comes back, it needs a visit. ### If the fridge side is warm with Sub-Zero EC50, could it just be a door left open? Sub-Zero says that is unlikely once temperatures are high. A warm fresh food section with EC50 points to a real cooling issue and calls for a service visit. Leave the code on the display for the technician. ### When is it fine to clear EC50 on my Sub-Zero myself? When the fresh food temperature is close to normal. In that case clean the condenser first, then hold the bell key for 15 seconds. On Designer models also make sure a custom toe kick is not covering the kickplate completely. --- **[Read on the site: Sub-Zero refrigerator showing EC50](https://refrigeratorrepair.center/error-codes/sub-zero-ec50/)** **[Book a visit with RefrigeratorRepair.center](https://refrigeratorrepair.center/schedule/)**
